Know that there are two kinds of stars - the heavenly and the earthly, the stars of folly and the stars of wisdom. And just as there are two worlds, a Little World [the Microcosm, man] and a Great World [the Macrocosm, the Universe] and just as the little one rules over the great one, so the stars of the microcosm rule over and govern the stars of heaven.

Paracelsus (1493–1541)
